| Test condition | Classification of isolates [no. correct/total (%)] |
||
|---|---|---|---|
| VISA | VSSA | hVISA | |
| VISA vs VSSA SVMa without hVISA | 21/21 (100) | 38/38 (100) | NAb |
| LOOCV VISA vs VSSA SVM without hVISA | 21/21 (100) | 37/38 (97) | NA |
| hVISA identification with VISA vs VSSA SVM | NA | NA | 13/21 (62) |
| hVISA/VISA vs VSSA SVMc | 21/21 (100) | 38/38 (100) | 21/21 (100) |
| LOOCV hVISA/VISA/VSSA SVM | 21/21 (100) | 34/38 (89) | 16/21 (76) |
a
SVM performed with the 14 peaks identified by forward stepwise multiple regression to maximally separate VISA from VSSA.
b
NA, not applicable.
c
SVM performed with the 25 peaks identified by forward stepwise multiple regression to maximally separate hVISA/VISA from VSSA.
